Calling all creators! What would you build to make the world better? Show us using cardboard, craft supplies, LEGOs and more; all construction materials will be provided. Work on your own or as a team! Prizes will be awarded for the top creations. While others are buidling, check out Sphero, play board games and/or video games, and tinker with LEGO Mindstorms! No registration required. Bring friends!
